Best iPhone Battery Case

I am constantly checking my social media feeds on my iPhone 5. I have been looking at Best Buy to find one, but they haven’t hit the shelves yet. Check out the best iPhone 5 battery case I could find from Amazon if you need that extra juice. I use it mainly when I am traveling. The time I spend waiting in line at security and waiting for takeoff drains my battery. According to the website, it gives you an additional 1.2 times the internal batter life.
